Fifteen people aged 11 to 25 were injured in a shooting at a Miami nightclub early on Sunday, a police spokeswoman said, adding that it was unclear who was responsible.

One person was in a critical condition after the shooting occurred at about 1 a.m. ET, Miami Police Department spokeswoman Frederica Burden said.

Police did not know how many shooters were involved or how many shots were fired at the club called The Spot, she said.

"We're interviewing some of the witnesses at this point," she said.
